IMPROVEMENT IN MACHINERY FOR PU'LVERIZING AND CRUSHING QUARTZ.

Specification forming part of Letters Patent No. 39,899, dated September15, 1863 antedated June 29, 1862,

To all whom it. may concern:

Be it known that I, JULIUS (J. DICKEY, of SaratogaSprings, in the countyof Saratoga andState of New York, haveinvented a new and Improved Modeof Constructing Machinery for Crushing and Pulverizing Quartz, Iron Ore,& c.; and 1 do hereby declare that the following is a full andexactdescription thereof, refercnce being had to the accompanyingdrawings, and to the letters of reference marked thereon.

Figure l is a perspective view of the machine; Fig. 2, a longitudinalsection through the same; Fig. 3, a vertical section of the ring G. Theframe A is to bewholiy or in part of iron. The crushing-drum. which isformed of two sections or halves, B B, secured together with bolts C, isrevolved by power applied to pulley D in the bearings E in the mainframe. Within the drum is seen red the ring G. (Seen detached in Fig. 3The axle of the drum is hollow, Fig. 2, and to the induction end Ithereof is'adapted a hopper, K, with a bent spout, L, the hopper beingfor the reception of the broken rock, which is thus introduced into themachine. To the opposite or eduction end M of the axle is adapted ascreen, :0, of wire -gauzcorother suitable material, for the purpose ofsifting the pulverized stone, only that which is sufliciently finebeing-allowed to pass through the screen. The powdered rock isthrown'into the screen by the action of the quartz in the drum, thispart of the operation being facilitated by the form of the case, asseenatf, Fig. 2. In the ring G, Fig. 3, I make the holes I, throughwhich the crushed or pulyerized quartz passes out of the drum. Hole'smay be also made in the sides of the drum B B for the same purpose. Theform of these holes may be round, conical, square, or other desirableand useful form; 1

. contemplate making holes through the ring G or drum only when the useof the screen Ois discontinued, and when the drum is used for crushingquartz for macadamized roads, iron ore, &c. Bound balls may be used toadvantage in the drum to facilitate the crushing of the quartz. Thechisel n, Figs? 1, 2, and 3, maybe made to screwinto the ring G or madepermanently on-said ring. These chisels may be made'of any desirableform and secured to the sections B B of the drum as well as to the ringG. The projections .9, Figs. 2 and 3, are made of any desirable andeflicient form. These projections may be also made on or secured tosections B B of the drum, as well as to the ring G. These projectionsand chisels greatly facilitate the crushing and ymlverizing of thequartz by the quartz being forced against said chisels and projections.

When the drum is made sufliciently large to receive several hundredpounds of quartz, the crushing and pulverizing of the quartz'is greatlyfacilitated by the action of quartz upon quartz.

In some cases I contemplate discontinuingthe useof theringGand makingthe. sections B B of the drum answer the purpose of the ring by makingthe projections of said sections B B, where they lap onto said ring,longer and so as to unite, in which case I make theprojections, &c., onthe inside of sections B B of the drum.

I contemplate making the form of the drum square, round, orotherdesirable and efiicient form.

It is manifest that the form and arrangement of the parts maybe somewhatvaried without a departure from the-spirit of my invention.

I Having now set forth the nature of this invention, and explained themanner of carrying the same into effect, I wish it to be understood thatwhat I claim as my invention, and desire to secure by Letters Patent,is-

Crushing and pulverizingquartz in the revolving drum B B when the quartzpasses into said drum through the induction end I, and when the saiddrum is provided with the screen 0, or its equivalent.
